Specification of Letters Patent.

Patented Oct. 4, 1910.

Application filed February 4, 1910. Serial No. 541,995.

To all whom it may concern:

Be it known that I, Gnonen F. BALLOU, citizen of the United States, and resident of borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-VVriting Machines, of which the following is a specification.

My invention relates to typewritin maparticnlarly to tabu ating mechanism.

In tabulating mechanism heretofore employed it has been customary to use column stops adjustable along a column stop bar to different positions corresponding to each index on the carria e scale or to each letter space position of t e carriage in its line of travel. In the use of such column stops considerable time was required to set them or adjust them when a change from one character of work to another was made and thework involved in determining where to set the stops was somewhat troublesome.

One of the objects of my present invention is tojoverc'ome these diihculties and to provide comparatively simple and eflicient mechanism for quickly determining the position of arrest of the carriage by the tabulator mechanism and for readil setting the tabulator mechanism according y.

A further and main object of my inven- I tion is to provide simple and efiieientmeans for clearing, or restoring the set stops to inoperative position.

To the above and other ends which will I hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations .of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters designate corresponding parts in the'various views, Figure 1 is a fragmentary side elevation partly in section showing a sufiicient number of parts of one form of typewriting machine to illustrate my invention in its embodiment therein. Fig. 2 is a fragmentary plan view of the same. Fig. 3 is a fragmentary vertical' transverse sectional view of the same with parts broken away and arts omitted, the section being taken on a ine rc-a in Fig. 1 and looking in the direction of the arrow at said line. Fig. 4 is an enlarged detail perspective View of the resetting cam for re-setting the column stops to inoperative position. Fig. 5 is a detail perspective View of the guide on which said cam is mounted for movement. Fig. 6 is an enlarged detail side elevation partly in section showing parts of the tabulating mechanism and the associated parts by which the column stops are moved to and from operative position. Fig. 7 is a detail perspective view of one of the column stops.

I have shown my invention in the present instance embodied in a No. 11 Remington typ'ewriting machine which contains a denominational tabulator. It should be understood, however, that the character of machine and of the tabulating mechanism employed is immaterial, so far as my invention is concerned.

My present invention is in the nature of an improvement upon the construction disclosed in the application of Victor Albert Emanuel Sivertsen and Janis Christian Nielsen, filed April 8, 1909, Serial No. 488,675.

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. A. carriage 4 is provided with grooved rails 5 which receive anti-friction balls or rollers G, the latter being likewise received in fixed grooved guide rails 7 to support the carriage in its movement from side to side of the machine. The carriage carries the usual cylindrical platen 8. The front bar of the carriage is provided with a carriage scale 9 with which a pointer 10 cooperates, the pointer being secured by a screw 11 to the forward fixed carriage rail. Projecting rearwardly from the carriage are arms '12 which are fixed to the carriage by screws 13 and have secured thereto at their rear ends a column stop bar 14, screws 15 connecting the column stop bar to said arms. 'The column stop bar is, as will be seen more particularly upon reference to Figs. 3 and 6, provided with two series of cylindrical openings 16, one series arranged above the other, the openings of the upper series being staggered with reference to those of the lower series. The upper series of openings receive substantially cylindrical.colunm stops 17 which are adapted'to slide fore and aft of the machine in said openings and into and out of opera tive position. Each stop 17 is beveled on its right-hand side as indicated at 18 in Fig. 7

- will hereinafter more clearly appear.

and each of these stops is likewise flattened on its upper side at 19 for cooperation with the inner fiat end of a screw 20 received in a tapped opening in the column stop bar 14. Each screw 20 thus prevents the associated substantially cylindrical stop 17 from turning in its bearing opening. Each of the stops 17 is likewise provided with two notches 21 and 22 in the flattened face thereof. A leaf spring 23 is secured in place by each of the headed screws 20 and is bent downwardly at its free end as at 24 for cotiperation with the notches 21 and 22 in the associated column stop. The springs thus constitute individual spring means for each of the stops 17 to mamtain it against accidental displacement in either the projected or operative position shown in Fig. 6 or in the inoperative position where the stop is moved forwardly until the end 24: of the spring is seated in the rear notch 21. Each of the stops 1.7 is reduced at its forward end portion as indicated at 25 for purposes wl ili ch ne lower series of cylindrical openings 16 in the column stop bar likewise receives a series of stops 26 which are formed like the stops 1? except that the flattened face 27 and the grooves or notches 28 and 29 therein are on the under sides of the stops, and the leaf springs 30 for retaining the lower series of stops in either the operative or inoperative positions are connected to the lower side of the column stop bar by screws 31. By this construction it will be understood from an inspection of Figs. 2 and 3 that the column stops of the two series are arranged in staggered relation and overlap one another in vertical planes although the contact faces 32 and 33 of each adjacent pair of stops 17 and 26 are arranged a letter space distance apart. By this construction I am enabled to provide comparatively thick or heavy column stops and nevertheless to situate the contact faces thereof at a letter space distance apart.

As hereinbefore explained when the column stops 17 and 26 are projected rearwardly as shown by the column stop 17 in Fig. 6, they are in the operative position where they are adapted to cooperate with tabulator or denominational stops 3% when the latter are projected forwardly by their key-controlled mechanism. In the present instance I have shown a form of denominational tabulator employed in the No. 11 Remington machine, though it should be understood that for the purposes of my pres ent invention any desired form of tabulating mechanism may be employed to coiiperate with the column stops. As shown in the present instance the denominational stops constitute parts of upwardly extending denominational stop levers 35 pivoted at 36 in a tabulator frame 37 secured by screws 38 and 39 to the frame of the machine. The

lowers ends of these denominational stop levers are connected to push links etO which in turn are connected to the depending arms of angular actuating levers 41 pivoted on a rod 42 secured to the base of the machine. The forwardly extending arms of these angular levers are operatively connected to key stems 43 guided in openings in guide plates as and d5. Restoring springs 46 are each connected at one end to the guide plate 45 and at the opposite end to the depending arm of one of the angular levers 41. A depression or" one of the denominational tabulator keys 4? is etl'ective to project the associated denominational stop 3% forwardly into the path of the column stops 17 and 26 which have been moved to operative positit In order to select and proje column stop to operative po; provided projecting means wl ion is cooperative with the column stops independently to move any desired one of hem at a time to ope *ative position. the part lar stop which may be projected to operative position pending on the position of the carriage in its line or" travel. Thus have provided actuating arm, finger o projecting device 48 formed as an upwa r y extending crank arm which projects iron a hub i8 secured to a rock shaft 49 mounted to turn in bearings in bracket 50 secured to the top plate of the machine by screws 51. i

From an inspection of 2 and 3 it will be seen that the arm at; is bent to the right to brin the end portion thereof just to the right of the left-hand or decimal stop or" the series of denominational. stops. This arm extends forwardly of the column stop bar it and forwardly of the column stops carried thereby and at each letter space movement or" the carriage a column stop is brought into register with the contact portion of the setting or actuating arm 48, the stops of the upper and lower series alternating in their cooperation with the arm 48 as the carriage moves successive letter space distances along the line of its travel. The reduced forward ends 25 of the column stops enable the arm 48 to co-act with each individual step without contacting with the adjicent stops. AS the at 1 48 moves rearwardly one of the column stops moved from its foremost position rearwardly to operative position as shown in Fig. 6. The pressure of the arm 48 on the co-acting column stop overcomes the pressure of the associated spring 24 or 30; the inclined sides Ofille groove or notch in which the spring is seated camming the engaging end of the spring out of the notch and affording a movement of the stop rearwardly until the engaging end of the spring is seated in the foremost notch in the stop, thus lockin it against accidental displacement from the operative. position. The rock jecting crank arm 53 to which is connected adownwardly extending link 54 bent as indicated at 55 to clear the top plate of the machine at the rear edge thereof. The lower end of the link 54 is con'nectedto a key lever 56 fulcrumed on a plate 57 and provided with a restoring spring 58. This key lever preferably extends to the key board of the machine'where it is provided with a special key 59 by which the rock shaft and the projecting device 48 may be moved to project the selected column stop. to operative position. I

In order to quickly restore all of the column stops to inoperative position or to move them forwardly on the column stop bar, I have provided a .re-setting, clearing, restoring device, wiper or cam designated-as a whole by the reference numeral 60 as shown in detail in" Fig. 4. This cam is provided with'inclined faces 61 on the right and left hand sides thereof, The member 60 is grooved on opposite sides at 62 for the re ception of upwardly extending guide arms 63 forming part of a bracket 64 which is shown in detail in Fig. 5. This bracket is secured by screws 65 (see Fig. 3) to the upper forward end of the tabulator frame 37 to guide theniember 60 in its up and down movements. One of the arms 63 is cut out as indicated at 66 to receive a pin 67 secured to the member 60 and extending into the cut-out 66 to limit theup and down movements of the member 60. The member 60 is recessed vertically, as indicated at 68 in Fig. 6, for the reception of a coiled expansion spring 69, the lower end portion of which surrounds a in 70 secured to the bracket 64. This spring normally maintains the restoring device. 60 in the elevated position where it is out of the path of the rearwardly projected column stops. When,however, the member 66 is depressed by hand against the pressure of the spring 69, the inclined or cam faces 61 are brought into the paths of the two series of column stops 1 7 and 26 which are in the operative position. If at this time the carriage is given a complete movement in the direction of its travel, either from left to right or vice versa, all of the operative column stops will be moved successively into cotiperation with the rc-setting cam 60 and the will be successively moved by one cam ace 61 or the other rearwardly against the pressure of the retaining springs 23 or 30 to the forward or inoperative position where they will no longer coiiperatewith any of the projected denominational stops. It will thus be seen that by a single movement of the carriage throughout its entire run from ri ht to left or vice versa the entire set of pro ected column stops will be successively restored to on the carriage scale 9.

normal or inoperative position. When the column stops have been thus restored to inoperative position pressure on the restoring device 60 is released and 1t 1s moved up.-

wardly to inoperative position by its spring 69.

In the present instance I have utilized th bracket 6l to constitute a part of the guiding means for the denominational stops. Thus from an inspection of Fig fpit will be seen that I have formed on the bracket a series of'teeth 71 with interdental spaces in which the denominational stops 34: are received at their upper edges and adapted to move. The lower edges of the denominational stops are in the present instance received in interdental spaces between like teeth on a plate-72 secured by screws 73 to the upper forward face of the tabulator frame 37.

From the foregoing description it will be observed thatthe projecting or selecting device 48 is carried upon the frame of the machine, whereas the column stops are carried upon the carriage. It will also be observed that the restoring device 60 by which the column stops are restored to normal position is carried by the frame of the machine and when it is in the operative position it is effective, by the movement of the carriage, to restore the column stops to normal or in;- operative position.

In the use of the devices it may be assumed, for instance, that a letter is to be written in which vertical rows of names or items and amounts are to appear, which items and amounts in different lines are to be placed exactly under each other. The carriage is moved to the position where the first letter of the first name or item is to be written. This may be assumed to be at 20, which is indicated by the pointer 10 The key 59 is then depressed and this effects a rearward movement of the finger, arm, projecting or selecting device 48 and effects a rearward movementof the particular column stop 17 or 26 which is opposite the contact portion of the column selecting finger or device. Said column stop is thereby moved to operative position where it is retained against accidental displacement by its coiiperative spring until the stop is restored to inoperative position. Thereafter and during the tabulating operation the projected column stop will coact with the decimal stop, or the first of the denominational stops counting from left to right, at the same point, 20, in the travel of the carriage where the carriage was arrested to select the column stop, and inthe desired position where the first name or item to be written is to be started. If the oper- 'ato'r desires to set the next column stop to write, for instance, an amount in the same line so that the decimal point Wlll he at say 50 on the carriage scale, it is only neces- 7 moving the carriage in the direction of its sary to press down the key 59 when the carriage is moved to a position where the decimal point may be written in a position which corresponds to 50 on the carriage scale. This projects the column stop at 5O to arrest the carriage at such position when the decimal key is depressed. If in the next and subsequent lines a name or item and an amount are to be written exactly under the first ones, no further setting of the travel while the cam is maintained in operative osition. New column stops may then be in ividually and successively selected and set in the manner hereinbefore pointed out. It will be understood that a material ad vantage of the invention is that the column stops are, by pressure exerted on the key 59, individually set up while writing the first line so as to'avoid calculating before-hand the positions where the stops are to be set, the position of the carriage in the present structure aiding in determining the selection of the column stop to be used for that particular point of arrest.

In'accordance with the present invention 7 I prefer to employ a stop for each index on the carriage scale or for each letter space position of the carriage, or at any rate for each index on the carriage scale or each letter space position of the carriage where ordinarily such stops might be employed and to provide means whereby each of said stops can be thrown into and out of operative posi. tion.

Variouschanges may be made without de-.

parting from the spirit and scope of my in vention.
